Roxy poked her head into the computer center.
"I'll be back soon, Miss Apricot.
I need to help Principal Penn."
Roxy glanced at Terrell and nodded.
He nodded back.
Then Roxy ran out of the school and shot into the air.
She found Detective Smith inside Metro City Central Bank.
The door to the bank safe was open.
The detective was knocking on it.
Roxy grinned. "The door is open, Detective.
You don't have to knock."
"Very funny, Rocket Girl." Detective Smith frowned.
"I'm wondering how the thief got into the safe."
The bank teller stood behind Detective Smith.
"It doesn't make any sense.
The safe isn't broken.
There's no hole in the wall.
I don't understand how someone stole the money!"
"Did you see anyone suspicious?" Roxy asked.
The teller shook his head.
"There are no clues," Detective Smith said.
"This is very odd." Just then his phone rang.
"Hello? Uh-oh. We're on our way!"
Detective Smith looked at Roxy.
"True Savings Bank was just robbed.
We need to—Rocket Girl?"
Zoom! Roxy flew to True Savings Bank and rushed inside.
A woman ran over.
"Rocket Girl! I'm glad you're here.
I'm Mrs. Betz, the bank manager.
We were just robbed!"
"Yes, I know," Roxy said.
"Did you see the robber?"
Mrs. Betz nodded. "I saw her escape."
Roxy ran back to the door.
"Which way did she go?"
Mrs. Betz sighed. "She didn't go out the door. She—"
Detective Smith ran into the bank. "Are we too late?"
"Yes," Roxy said. "But luckily, Mrs. Betz saw the robber."
Roxy turned back to the bank manager.
"Tell us what you saw."
Mrs. Betz led Roxy and Detective Smith into a safe.
"It sounds ridiculous," she said.
"But there was a spinning, glowing hole right here in the wall.
A woman was grabbing money and throwing it into the hole.
I told her to stop, but she ignored me.
She threw the rest of the money in.
Then she jumped into the hole, and the hole disappeared.
Now it's a solid wall again."
"Hmm." Roxy knocked on the wall.
"Maybe it was a wormhole."
"Huh?" Detective Smith said.
"A wormhole," Roxy said.
"It's like a tunnel through space.
It connects two different places.
I didn't think wormholes were real though."
Detective Smith's phone rang again.
"Hello?" As he listened, the color drained from his face.
He hung up the phone and looked at Roxy.
Detective Smith swallowed.
"Every bank in Metro City has been robbed!"
